Is there a way to disable Candlestick aggregation in lightningchart js

Question

I am trying to make an application for stocks with lightningchart js. I tried to put 30 days of 1-minute data into the chart but it is aggregating candles.

This is my code

const { lightningChart, emptyFill, OHLCFigures } = lcjs;

const chart = lightningChart().ChartXY({ container: document.getElementById('chart-root') })
const ohlcDataArr = []; // contains 30 days 1-min data [date, open, high, low, close values]
const series = chart
            .addOHLCSeries({ positiveFigure: OHLCFigures.Candlestick })
            .add(ohlcDataArr);
chart.getDefaultAxisX().fit();
chart.getDefaultAxisY().fit();

Only about 40 or 50 candles are shown but should be 43,000?

Is there a way to turn off candlestick chart aggregation?

To disable the aggregation call ohlcSeries.setFigureAutoFitting(false).

const { lightningChart, emptyFill, OHLCFigures } = lcjs;

const chart = lightningChart().ChartXY({ container: document.getElementById('chart-root') })
const ohlcDataArr = []; // contains 30 days 1-min data [date, open, high, low, close values]
const series = chart
            .addOHLCSeries({ positiveFigure: OHLCFigures.Candlestick })
            .setFigureAutoFitting(false)
            .add(ohlcDataArr);
chart.getDefaultAxisX().fit();
chart.getDefaultAxisY().fit();

Thanks! I can't vote up your answer as Im too new but I will try it — Viktor Sudakov, Nov 18 '21 at 16:49
